That's pretty good Keith ! i am just watching and learning from you and Andrew with the tools both in your hands makes every thing else made in the past looks primitive ...both very professional televisors /

The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.

Here is another video that's acutally in focus. Lots of flicker though. You can see there are thin black lines or gaps between the lines. I am going to cut another Nipkow disc soon and expand the aperture width 20% to see if they will go away. I have a new camera coming soon too so hopefully I can get some flicker free video
